A game-theoretic approach for power control in a full-duplex femto-relay network

摘要

Transmission power control methods appear to be the most conventional practices to enhance system capacity and to mitigate the effects of cross-tier and co-tier interference of small cell networks (e.g. femtocell networks). Additionally, full duplex communications appear to be a novel solution for the increase in the spectrum efficiency and the reduction in latency for mobile stations. In this paper, we propose an algorithmic game method for power control of a femto-relay network that implements the full duplex communication between its nodes and mobile stations. Our proposed approach shows that the corresponding game sustains a Nash equilibrium by a small number of iterations that is near to the number of femto-relays in the network in the presence of self-interference. Moreover, we show the effects of self-interference on the overall system power.
